THE ATMOSPHERIC AIR QUALITY ANALYSIS AND THE HEALTH RISK ASSESSMENT FOR THE KAZAN CITY POPULATION (THE REPUBLIC OF TATARSTAN)

Abstract

Monitoring of atmospheric air in the city of Kazan was performed based on average annual concentrations of the Air Pollution Observation Stations (APOS) of three administrations: The Federal Budgetary Healthcare Institution �Center of Hygiene and Epidemiology in RT (Tatarstan)� (FBHI �H&E Center in RT�), Ministry of Environment and Natural Resources of RT (MEPNR of RT) and Federal State Budgetary Institution �Territorial Administration for Hydrometeorological and Environmental Monitoring in RT� (FSBI �TAHEM in RT�). Two Kazan districts with population size equal to one third of the city (the Vakhitovsky and the Sovetsky ones), where APOS of all three administrations were compactly located, were identified for the study. Control data differ in pollutants priority and quantitative estimation of certain pollutants. Non-carcinogenic risk evaluation results on chemical effluence with vehicle emissions had no discrepancies (unacceptably high total risk level in Vakhitovsky and Sovetsky city districts, HI was greater than 6.0); however, danger coefficients obtained from the data of the Federal State-Funded Healthcare Institution �Hygienic and Epidemiological Center in the Republic of Tatarstan� far exceed similar results of other agencies. Verification of the available sampling techniques and development of a single approach to analysis and evaluation of the environmental pollution by harmful substances are required for a consistent risk assessment by monitoring agencies.
